AI Technical Summary

Benefits of technology

The text describes the discovery that certain types of ethoxylated oils, such as macadamia nut oil, help to improve skin hydration when mixed with water and applied topically. This is because the ethoxylated oils can trap water in emulsions, and mimic the fatty acids found in the skin's natural oils. Overall, this technology helps to enhance the skin's natural moisturization process.

Problems solved by technology

However, a significant number of people continue to suffer from dry skin symptoms.
Furthermore, as people age, their skin loses elasticity, and decreases in the ability to retain moisture.

General Procedure for Human Clinical Trials

[0114]This Example describes a general procedure developed for the human clinical studies that were carried out to evaluate the mixtures described herein for their effectiveness in improving skin hydration or moisturization.

[0115]Changes in skin conductance, impedance or capacitance were used to study epidermal hydration in vivo. Measurements were made to determine the difference in dielectric constant of the skin. Typically, skin has a low dielectric constant, and water has a high dielectric constant of 81. When skin is hydrated, conductance and / or capacitance increases and / or impedance decreases. A Corneometer® CM 825 (Courage+Khazaka Electronic, Germany) was used to measure changes in the electrical capacitance of the test subject's skin which is reflective of the changes in hydration or moisturization level of the skin surface. The measurements were based on capacitance measurement of a dielectric medium. The measurement can detect smal...

Clinical Evaluation of the Efficacy of Test Product 1 Mixture Containing 1% PEG-16 Macadamia Glycerides and Water

[0120]Clinical studies were conducted according to the general procedure described in Example 1 herein above. Under conditions of the study, a total of 15 healthy female subjects, 35-65 years of age, completed the clinical study evaluating the efficacy of a mixture containing 1% PEG-16 Macadamia Glycerides oil and deionized water (or “DI Water”). A summary of key clinical findings is shown in Table 1.

Abstract

The present disclosure generally relates to approaches for improving water absorption and retention by the skin's surface. In particular, the disclosure provides compositions and methods for preparing mixtures comprised of ethoxylated oils and water or mixtures comprised of micro or nano emulsions and water, which provide enhanced skin hydration or moisturization to a subject.

Description

BACKGROUNDField of the Invention[0001]The present disclosure generally relates to approaches for improving water absorption and retention by the skin. In particular, the disclosure provides for compositions and methods for preparing mixtures which provide enhanced skin hydration and / or moisturization.Description of the Related Art[0002]Skin covers the entire human body and provides a protective barrier from various types of external stimuli and damage. The skin also protects against a loss of moisture, referred to as dehydration. Structurally, skin is a multi-layer membrane with a highly complex structure, and includes the epidermis, the outmost epithelial tissue of skin. The epidermis is mainly constructed of keratinocytes, and is composed of four layers—the stratum corneum, the stratum granulosum, the stratum spinosum, and the stratum basale. The outermost layer of the epidermis, stratum corneum, consists of dead cells (corneocytes). The primary function of the stratum corneum is ...
